Watch for wind slabs at upper elevations.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–1.5
    Recent wind has formed slabs in exposed terrain in the alpine and at upper treeline elevations. A buried crust on south-facing features may increase the likelihood of human triggering.

Confidence

Moderate - Wind speed and direction is uncertain

Weather Forecast

FRIDAY NIGHT: Cloudy with isolated flurries, light southwest wind, alpine temperatures drop to -8 C.SATURDAY: Cloudy with sunny periods, light wind, alpine high temperatures around -5 C.SUNDAY: Sunny with cloudy periods, light wind, alpine high temperatures around -8 C.MONDAY: Sunny with cloudy periods, moderate northwest wind, alpine high temperatures around -8 C.

Avalanche Summary

No recent avalanche activity has been reported. On Wednesday, numerous size 2 loose dry and storm slab avalanches were reported on all aspects in the south of the region, particularly in the Cheam area where the storm slabs were thicker.

Snowpack Summary

5-15 cm of low density snow sits above a mix of hard wind affected snow and possibly crusts on south-facing features. Several crusts can be found 40-80 cm below the surface. At higher elevations cold temperatures have been working to facet and break down these crusts. In sheltered terrain at and below treeline, a layer of weak feathery surface hoar or sugary facets may be identified around these crusts, but this interface has produced little recent avalanche activity. The remainder of the snowpack is generally well-settled.
